Specification of Letters Patent. Patented Ai g, 10, 1920,

Application filed March 20, 1920. Serial No. 367,326.

To all whom it may concern:

I Be it known that 1, CHARLES W. Ho'r'r- MANN, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Mixer and Separator, of which the following is a specification. I

My present invention comprehends a novel construction and arrangement of a mixer and separator wherein novel means are employed to impart to a container an eccentric movement during its rotation.

It further comprehends a novel construction and arrangement-of an inner container and an outer casing and novel means for actuating the inner container.

Other novel features of construction and advantage will hereinafter more clearly appear in the detailed description.

For the purpose of illustrating my invention, I have shown in the accompanying drawings typical embodiments thereof which are at present preferred-by me, since said embodiments will be found in practice to give satisfactory. and reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not; limited to the precise'arrangement and organization of these. instrumentalities as herein shownand described.

Figure 1 represents a front elevation partly in section of a mixer and separator embodying my invention. V

Fig. 2 represents an end elevation of the construction seen in Fig. 1.

Fig. 3 represents in elevation the opposite end from that seen in Fig. 2.

i Fig. 4; represents a section on line 4-4 of Fig. 1.

Fig. 5 represents a longitudinal section of another embodiment of my invention.

Similar numerals. of reference indicate corresponding parts.

Referring to the drawings.

' 1 designates the base or supporting framework of a mixer and separator embodying my invention. 2 is a shaft journaled in the base 1 and having fixed to it the lower ends of the crank arms 3 which at their upper ends are slotted as at 4 to receive the crank pins, 5 secured to the crank disks 6 which latter are mounted on the shaft 7. This shaft 7 is driven in any desired manner and as illustrated is provided with pulleys 8 which are driven by any desired source. of power. One of the crank arms 3 is offset to provide for the assembling of the pulleys 8 on the shaft 7. The shaft 7 carries a pinion 9 which meshes with a gear 10 fixed to one of the stud shafts 11 which latter are fixed to the rotatable article container 12 in any desired manner. The stud shafts 11 extend into the crank arms 3 and are rotatably journaled therein so that the rotatable article container 12 is carried and supported by such crank arms. The journals 13 of the shaft 7 are supported on an outer casing li, the ends of which are provided with apertures 15 through which the stud shafts 11 pass and these apertures are of sufficient size to permit the eccentric travel of the stud shafts 11 which is occasioned by the crank arms 3.

The container 12'is provided with guides 16 for a sliding door or closure 17 which controls the replenishing and delivery opening 18. The casing 141 which is stationary has a discharge outlet 19 at its bottom formed by a spout 20. The casing 14; is provided near its upper end with a door 21 hinged to it at 22 and provided with a lock 23 which engages a member 24 carried by the casing H.

In the construction which I have just 7 described which relates more particularly to Figs. 1 to 4k inclusive, the device is used as a mixer and the wall of the article container 12 is unapertured. The only difference between the embodiment seen in Fig. 5 and that seen in the other figures is that the article container is foraminated and in order to illustrate one type of such container, I have shown the wall thereof as being provided with amultiplicity of apertures, although the result which it is desired to attain may be accomplished by employing many different types of containers.

In this embodiment seen in Fig. 5 the actuating mechanism is the same as that already described in connection with the other figures and I have therefore deemed it unnecessary to describe such parts in detail as it would involve needless repetition and I have applied to corresponding parts the same reference character.

The article container 25 as in the case of the article container 12 may have any desired contour but is preferably made cylindrical having closed ends but in the case of the article container 25, in Fig. 5, one end is provided with the openings 26 through an end wall in order that the material may be fed into the inner container from a hopper 27 which extends through an opening in the 30. It will of course be understood that the 7 article container25 is provided with a re-.

movable closure whereby the material may be; emptied therefrom similar to that shown in Figs. 1 to 4 inclusive and the outer casing 14 is in a similar manner provi'dedwith a discharge outlet corresponding to the dis- 7 charge outlet 19.

The operation of my novel mixer and separator will now be readily. apparent to those skilled inthis'art and is as follows 2- Referring first to Figs. 1 to 4-,inclusive the materials which are to be mixed are placed in the article container 12 and the door 17 closed and the door or closure 21 is also closed. The machine is now started thereby causlng the shaft 7 which 1s the main drivingshaft to revolve and as this.

' shaft is intergeared with the article container 12 such article container :will be continuously revolved. During its revolution, however, aneccentric movement is imparted to it since such article container isjournaled in the crank arms 3 which are actuated by the crank pins 5 carriedby the crank disks .6 which are secured to the main. driving shaft 7, Y I I V g 7 As soon as the materials which have been placed 1n the article container 12 have been mixed to the desired degree or extent the machine is stopped,'the door 17 is opened and the mixed material is discharged through the opening 18 into the outer casing 14 and discharged from such outer casing 14 through the discharge outlet 19 whic is formed by the spout 2Q. 1

In theembodiment seen in Fig. 5 the operationis the same except that the smaller material or materials which are of such contour that they will pass throughthe apertures 29 will be separated and pass into the outer casing 14 and be discharged therefrom through its outlet. The article container 25 is driven in a similar manner and has the same movement as that of the article container 12- which has already been described.

It. will be seen that the article container in each case is mounted in crank arrnswhich are driven by a crank pin and at the same time a continuous revolution of the article container is efiected since such article container is intergeared with the driving shaft 7 which carries the crank disks 6 which effect the operation of the crank arms 3.

it will nowbe apparent that I have devised a novel and useful construction of a mixer and separator which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description, andwhile 1 have, in the present instance, shown and described preferred embodiments thereof which will be found n practice; to give satisfactory and reliable results, it is to be understood that such embodiments are susceptible of modification in various particulars without departing frompthe spirit orscope of the invention' or sacrificing any of its advantages.

1 Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is: 1. In a device of the character stated, an outer casing having a discharge outlet and provided with an inlet opening, an article container within said outer casing, crank arms on which said article container is mounted, means to actuate saidcrank arms, and means to continuously revolve said article container;
